Abstract
A segment of roadway including a body and a strain sensor array embedded in the body. The strain sensor array includes vehicle-strain sensors configured to detect strain on the body resulting from vehicles traveling across the top surface. The strain sensor array includes an optical fiber cable comprising the plurality of vehicle-strain sensors, and the optical fiber cable is embedded in a configuration that includes a bend with a bend radius of at least twenty millimeters (20 mm). Each of the vehicle-strain sensors is separated from the bend by a length along the optical fiber cable of at least one centimeter (1 cm), and each of the vehicle-strain sensors is separated from each other of the vehicle-strain sensors by a length along the optical fiber cable of at least one centimeter (1 cm).
